Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. Available in a variety of colors. These IS headsets are for frames with molded-in internal bearing cups. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.
Any frame that uses IS (Integrated Standard) headsets with 41mm upper and 52mm lower outer bearing diameter.
Uppers and lowers sold separately.
Enduro stainless steel sealed bearings included on both the upper and lower.
IS42 is not compatible with Specialized bikes or bikes using the Campagnolo Hiddenset standard
Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately). (Never use a star nut on a carbon steerer tube)
The lower IS headset consists of only one bearing and one cone ring
